Chinosimudzira ruzha rwakaderera chinhu chakakosha mumasisitimu eRF/microwave, chinoshandiswa zvakanyanya kuwedzera masaini asina simba ukuwo chichideredza ruzha rwakawedzerwa. Mabasa ayo makuru nemamiriro ekushandiswa ndeaya anotevera:

Mabasa Ekutanga:

1. Kuwedzera kwechiratidzo
Wedzera amplitude yezviratidzo zvisina simba zvinogamuchirwa nemaantenna kana masensa kuti uve nechokwadi chekuti mashandiro anoitwa nemacircuit anotevera akadai sema mixers neADCs anobudirira.
2. Kuderedza ruzha
Nekugadzirisa dhizaini uye kushandisa zvinhu zvisina ruzha rwakanyanya, chimiro cheruzha chakazviunzira (NF) chinodzorwa mukati mehuwandu hwe0.5-3dB (ideal amplifier NF = 0dB).

Maitiro Ekushandisa:

1. Sisitimu yeradar
Muradar yemauto (yakadai seradar inodzora moto inofambiswa nemhepo) uye radar yevanhuwo zvavo (yakadai seradar yemagetsi ine millimeter wave), LNA inoshandiswa kuwedzera chiratidzo che echo chisina simba (signal-to-noise ratio SNR < 0dB) chinoratidzwa nechinangwa. Painopfuura nepakati pe amplification link neNF < 2dB, radar inogona kuziva zvinangwa neRCS iri kure kana yakaderera (radar cross section).
2. Sisitimu yekutaurirana isina waya
Amplifier yeruzha rushoma ndiyo chinhu chikuru che5G/6G base stations, satellite communications, uye mobile terminal receiving links. Ndiyo inokonzera low-noise amplification (NF < 1.5dB) yemasaini eRF asina simba (akaderera se -120dBm) anotorwa neantenna isati yabviswa masignal, zvichivandudza zvakanyanya kunzwisisika kwekugamuchira kwesystem. Semuenzaniso, mu millimeter wave frequency band (24 - 100GHz), LNA inogona kubhadhara kusvika ku20dB yekurasikirwa kwenzira, ichivimbisa kugadzikana kwekutumira data nekukurumidza.
3. Chishandiso chekuyedza chakanyatsojeka
Mumidziyo yakaita se spectrum analyzers uye vector network analyzers (VNA), LNA inoona zvakananga mashandiro eruzha rwechishandiso uye dynamic range. LNA inogona kuvandudza kunzwisisika kwechishandiso nekuwedzera chiratidzo chakayerwa chenV level kusvika kune effective quantization range yeADC (yakadai se1Vpp). Panguva imwecheteyo, ultra-low noise coefficient (NF <3dB) inogona kuderedza kusava nechokwadi kwekuyera uye kuderedza zvikanganiso zvekuyera.
4. Wedzera nzvimbo dzekushandisa
Kuongorora nyeredzi neredhiyo: Teresikopu yeFAST inoshandisa LNA inotonhodzwa nehelium (NF ≈ 0.1dB) kuti itore mitsetse ye21cm spectral iri muchadenga.
Kushandiswa kweQuantum: Kuwedzera masaini e μV level (4 - 8GHz) e superconducting qubits kunoda kushanda kweruzha rwe quantum.
Kufungidzira kwezvokurapa: Midziyo yeMRI inowedzera μV level nuclear magnetic resonance signals kuburikidza ne non-magnetic LNA, nekuvandudzwa kwechiratidzo-ku-ruzha kweanopfuura 10dB.

Qualwave Inc. inopa ma amplifiers ane ruzha rushoma kubva pa9kHz kusvika 260GHz, nenhamba yeruzha yakaderera kusvika pa0.8dB.
Modhi yeQLA-9K-1000-30-20, iyo yakagadzirirwa zvakanyanya kutsvagisa kwesainzi uye mashandisirwo ekutaurirana, inowana chiyero chakanaka chekushanda kwe30dB gain uye 2dB noise figure mu9kHz ~ 1GHz frequency band.

Kana muchifarira chigadzirwa ichi, ndapota musazeza kutibata. Tinofara kukupai rumwe ruzivo rwakakosha.
